If your diesel truck seems to be burning more fuel than usual, don’t be too quick to blame the pump prices. At Consolidated Truck in Many, Louisiana, we know from experience that poor fuel economy often comes down to simple, fixable issues that build up over time. Things like clogged air filters, misaligned tires, faulty sensors, or even your driving habits can slowly eat away at your fuel efficiency, especially in heavy-duty trucks that spend long hours hauling, idling, or working in the field.
It’s easy to overlook these small problems until you’re spending a lot more at the pump each week. And for fleet managers and owner/operators in industries like logging, agriculture, and municipal work, those costs add up fast.
At Consolidated Truck, we specialize in helping hard-working drivers across Sabine Parish and beyond get more out of every gallon. Whether you operate one rig or manage a whole fleet, we offer cost-effective fuel-saving services, from in-depth diagnostics to preventative maintenance, that are proven to improve fuel economy and reduce wear on your truck.
Our mission is simple: to keep you on the road, running efficiently, and making a living, with no surprises along the way. Let’s break down what you can do to get better mileage and how we can help.
Why Fuel Efficiency Matters (Even More Than You Think)
Operating costs are climbing. Fuel is often one of the biggest ongoing expenses for commercial trucks, especially if you’re running long distances or navigating stop-and-go routes. But boosting efficiency goes beyond saving money.
Better fuel use also means:
- Less wear on your engine
- Fewer breakdowns and shop visits
- Longer lifespan for key components
- Lower emissions and a lighter footprint
The best part? Most fuel savings start with small, manageable changes.
1. Keep Your Maintenance Routine Tight
Skipping maintenance doesn’t just lead to mechanical issues, it directly impacts how much fuel your truck consumes. Things like clogged air filters, overdue oil changes, and worn belts force your engine to work harder than it needs to.
To maintain better mileage for trucks:
- Replace air filters regularly
- Stick to your truck factory recommended maintenance schedule
- Keep fuel and oil filters clean
- Monitor your cooling system for efficiency
Small fixes can translate into big fuel savings over time.
2. Tire Pressure and Alignment Matter More Than You Realize
It might not seem like a big deal, but underinflated or misaligned tires are one of the most common causes of poor fuel economy.
Check your tires often for:
- Correct PSI based on load weight
- Even wear across the tread
- Signs of misalignment like pulling or vibration
If you drive daily and haven’t checked your alignment in a while, you’re likely burning more diesel than necessary. A proper alignment can improve fuel efficiency by up to 3% and reduce drag that slows you down.
3. Weight and Load Distribution Can Make or Break Efficiency
Not all hauling is equal. A poorly loaded truck, especially one that’s overweight or unbalanced, creates more resistance, affects braking, and stresses your suspension. This increases the workload on your engine, decreasing fuel efficiency without you realizing it.
Try to:
- Distribute cargo evenly across the axles
- Avoid overloading beyond the legal weight
- Secure freight to prevent shifting
Efficient load management is a simple but often overlooked part of better mileage.
4. Driving Habits That Cost You Fuel
Fuel savings aren’t just about the truck, it’s also about the driver. Habits behind the wheel make a big difference.
Avoid these fuel-draining behaviors:
- Excessive idling during stops or delays
- Quick acceleration and hard braking
- High-speed cruising over 65 MPH
- Unnecessary shifting or revving
Even modest changes in driving style can lead to measurable improvements. For fleets, training drivers on fuel-efficient techniques can pay off in both savings and smoother operation.
5. A Clean DPF = Better Fuel Use
Diesel Particulate Filters (DPFs) are designed to reduce emissions, but when they’re clogged or neglected, they increase back pressure in the exhaust system. This forces the engine to work harder and burn more fuel to maintain power.
If you’re noticing sluggish performance or excessive regeneration cycles, it may be time for a professional DPF cleaning. This service improves airflow and brings your truck back to optimal fuel use conditions.
What’s Robbing Your MPG Without You Knowing?
Let’s break it down. MPG stands for “miles per gallon”, how many miles your truck can travel on a single gallon of fuel. The higher your MPG, the less fuel your truck needs to cover the distance. So when your MPG drops, you’re spending more to go the same distance, and that adds up fast.
Most truck owners keep an eye on obvious things like tire pressure or load weight, but there are less visible factors that could be quietly dragging down your fuel efficiency.
- Aerodynamics: Even something as simple as a missing mudflap or damaged fairing can increase drag. Trucks with clean exterior lines perform better at highway speeds.
- Worn wheel bearings or brakes: If your wheels don’t spin freely, your engine’s doing more work to move forward, and using more fuel in the process.
- Low-quality fuel: Inconsistent fuel quality can affect combustion efficiency. Stick to trusted fuel sources and keep your fuel filters clean.
- Software or calibration issues: Modern engines rely on computer controls. If your truck’s ECM isn’t tuned or calibrated correctly, fuel delivery may be less than optimal.
These are things most drivers don’t check, but they can impact your wallet more than you’d think.

Small steps, big payoff. Staying on top of these details means less time and money spent at the pump.
Fuel-Saving Know-How: Answers from the Experts
Does using cruise control help save fuel?
Yes. On flat terrain or long highway stretches, cruise control maintains a consistent speed, avoiding the fuel-wasting habit of fluctuating acceleration. However, avoid it on hilly terrain, where it may cause unnecessary throttle increases. We often recommend combining cruise control with manual control on grades for optimal savings.
Can outdated software in older trucks reduce fuel efficiency?
Absolutely. If your truck’s software hasn’t been updated, it may not be running with the latest performance and efficiency calibrations. Our team in Many, LA uses OE software updates to keep systems current, which can improve engine response and reduce fuel consumption.
What’s the impact of air conditioning on fuel economy in heavy-duty trucks?
Running the A/C does use additional fuel, typically increasing fuel use by 0.5 to 1 MPG depending on vehicle size and load. While necessary for comfort, it’s worth monitoring usage during idle periods or low-speed driving. Idle reduction systems or bunk heaters may offer fuel-efficient alternatives.
Do aerodynamic upgrades help work trucks save fuel?
Yes, especially for trucks doing highway mileage. Fairings, cab extenders, and side skirts can significantly reduce drag. Even mudflap position and trailer gap spacing can affect airflow. We can inspect your truck for potential aerodynamic improvements during routine maintenance checks.
